According to a 2016 J.D. Power national report, switching from the utility company to an REP is not as attractive as it once was. Deregulated markets aim to drive down costs and encourage innovation but has really only succeeded in the second — the price gap between utility rates and retail rates has actually been closing. But deregulation has been successful in championing green energy and improving customer service. This improvement shows up in some impressively high J.D. Power ratings.
Over a year, you could save nearly $100 by choosing the green plan. But it’s important to note that Constellation’s attractive initial rates will very likely not be around for a second year. According to the customer reviews on Consumer Affairs, this new contract usually jacks up the price. It offers great rates for new customers, but it may not be worth it to stick with them for more than an initial contract.
As the leading producer of nuclear energy, the U.S. has some of the world’s cheapest electricity—which for the industrial sector averages between 6.75 and 9.33 cents per kWh. These prices are either trumped or competitive with other nuclear power-producing countries such as Russia ($0.11 cents per kWh), Canada ($0.10) and China ($0.08). India, which doesn't quite make it into the top 10, generates 30 billion kWh annually at an average of $0.08 cents per kWh.

The growth in wind power and natural gas fueled power will offset the loss in coal over time but for the summer of 2018, expected record demand for electricity will converge with power plant closures to put a squeeze on wholesale electricity rates. This, in turn, will cause the retail electricity prices paid by most Texas consumers to increase. The rise in wholesale rates could be particularly dangerous for consumers who have electricity plans that are tied directly to the wholesale price of electricity.
